Outline of Research at the Start

強電場により相転移が生じ分極が急激に増加する性質(メタ誘電性)をもつ誘電体は、電気エネルギーの貯蔵や機械/熱エネルギーとの相互転換機能への利活用の観点から、近年熱い注目を集めている。本研究では、環境適合性の高いエネルギーエレクトロニクスを実現するため、高性能のエネルギー貯蔵・変換機能をもつ有機分子材料の開発を行う。多様な分子自由度を最大限活用し、相変化型誘電体物質の拡充と新奇相を含む多様な強電場相の創出を図るとともに、強電場オペランド計測も活用し、相転移の微視的機構と構造-機能相関を明らかにする。これにより、強電場物質科学の学理の構築と、将来のデバイス開発を加速する材料設計指針の確立を目指す。

Outline of Final Research Achievements

Dielectrics, which have the rapidly increasing polarization with strong electric fields, are expected to show highly performing energy storage and conversion. In this study, we developed organic molecular phase-change materials in which a highly polarizable ferroelectric phase is induced by an external electric field. Through the expansion of variations in phase-change dielectrics and switching schemes, we were able to obtain new materials with high-polarization and low-energy loss as well as comprehensive understanding of the microscopic mechanism and structure-property relationship useful for effective material design.

Academic Significance and Societal Importance of the Research Achievements

巨大な分極変化を示す反強誘電体は、電気エネルギーの貯蔵や機械/熱エネルギーとの相互転換機能への利活用の観点から、近年熱い注目を集めてきた。四角酸で見出した静電エネルギー貯蔵密度と貯蔵効率は、有機分子系の中で群を抜く性能であるだけでなく、重量ベースであれば静電エネルギー貯蔵密度は無機のバルク反強誘電体の最高性能に匹敵、凌駕するレベルにあり、軽量な有機物ならではの優位性を発揮できた意味でも特筆すべき成果である。
